I have been trying to create a new file system on our VNX5800 and it keeps telling me that we have exceeded the number of mount points for server_2. I've done a bit of digging around and found with the output of a server_mount server_2 | wc -l there are 2082 mountpoints. However 371 are showing as unmounted (These were mounts created by the checkpoints which we have unmounted).

[nasadmin@ c0 ~]$ server_mount server_2 | wc -l

2082

[nasadmin@ c0 ~]$ server_mount server_2 | grep unmounted | wc -l

371

So my question is when you do a server_umount on a file system does it not actually free up a mount point because by my simple logic if there are 2082 total mounts and 371 listed as unmounted we are well below the maximum of 2048 mounts per data mover so i am failing to see why i cannot create a new file system/mount point.

Am i missing something obvious here? Any help would be appreciated.
